Always connect the positive lead to the 

battery before connecting the negative lead. This

electrical short caused by contacting the tractor 

body with tools being used to connect the cables.

Test and, if necessary, recharge the battery after the tractor has 

been stored for a period of time.

A voltmeter or load tester should read 12.6 volts (DC) or 

• 

higher across the battery terminals. See Fig. 7-2.

Charge the battery with a 12-volt battery charger at a 

• 

MAXIMUM rate of 10 amps.

A fuse is installed to protect the tractor’s electrical system from 

damage caused by excessive amperage. Always use the same 

capacity fuse for replacement. If the electrical system does not 

function, check for a blown fuse.
If you have a recurring problem with blown fuses, have the 

tractor’s electrical system checked by your Troy-Bilt Service 

Dealer.

There are several safety switches in the electrical system. If a 

function of the safety interlock system described earlier is not 

functioning properly, have the electrical system checked by your 

Troy-Bilt Service Dealer.
